<chuckle>  sendmail.cf was fun, but MMDF channels were so much more amusing –
and rather necessary in order to deal with gatewaying BITNET, phonenet, DECNET, 
X25NET, uunp, and ondemand dialup-ip ppp and cslip domains in a semi-reliable 
manner on the relay.cs.net <http://relay.cs.net/> and relay2.cs.net <http://relay2.cs.net/> servers.  

It didn’t help that many sendmail.cf files in those days shipped relay.cs.net <http://relay.cs.net/> preset as 
their default smtp relay host…  always made for large queues and careful editing.
